  • Touching the Tangled Sun
    One of the great mysteries for astronomers is why our Sun's surface is so much hotter than its core. The counterintuitive answer, according to a suite of solar observatories, hinges on the Sun's tangled magnetic field and deep, fiery waves.

  • Flying the Sun to Safety
    The Genesis spacecraft spent 27 months collecting atoms from the solar wind as they streamed off the Sun's corona. When the Genesis sample capsule comes hurtling back to Earth on September 8, helicopter pilots will be waiting to grab it out of the sky.

  • Whirly Bird Catches the Urn
    The Genesis mission will end September 8th, after capturing the first extraterrestrial samples to be returned since Apollo. The spacecraft has stowed pristine solar wind to help scientists search back in the planetary timeline.

  • What’s Up with Prominent Sun?
    Last November solar observers witnessed the largest solar flare ever observed. This month, the orbiting solar observatory snapped a spectacular image of the Sun ejecting an eruptive prominence, a relatively cooler gas ejection that stretched more than fifty Earth diameters and moved at 45,000 miles

  • Our Typical Dwarf Star
    A great mystery about our own star is why its atmosphere is hotter than its surface. By studying microflares, solar physicists believe some of this energy is coming from the smaller but more frequent explosions on our typical dwarf star.

  • Goldstone, We Had a Problem
    Scientists using the main solar observatory, SOHO, have been troubleshooting a locked antenna for weeks. If not solved, about a third of the year, the prediction of solar storms would be pushed back to a pre-1980's situation.

  • Neat! Comet Crossing
    Using tracking from automated telescopes, solar physicists captured the Sun's fiery greeting to a close-passing comet called NEAT. Initially thought to be a newly formed comet, NEAT turns out to have last visited the inner solar system 37,000 years ago.
